Description

一种调节日光温室草莓根圈环境温度的方法及设施A method and facility for adjusting the ambient temperature of the strawberry rhizosphere in a solar greenhouse

技术领域 technical field

本发明属于一种设施环境管理领域,特别是指一种在高架栽培槽上布置管道,用于冬夏季双向调控日光温室草莓根圈环境温度的方法及设施。 The invention belongs to the field of facility environment management, in particular to a method and facility for arranging pipelines on elevated cultivation tanks for bidirectionally regulating the ambient temperature of strawberry root circles in solar greenhouses in winter and summer.

技术背景 technical background

草莓属蔷薇科草莓属,为多年生草本植物,因其具有较高的经济价值,适应性广,适合设施农业周年生产。同时由于草莓是浅根性植物,根系对环境条件的要求比较敏感,特别是对温度的要求,表现为既不抗高温,也不耐低温。草莓根系生长的临界温度是2~5℃,在-8℃时会受冻害,-12℃时会冻死。根系生长的最适温度是13~23℃,25℃以上根系生长缓慢,温度最高限为35℃。因此,在草莓管理上,冬季必须采取有效的加温措施增加地温,以保证根系安全越冬,并促进根系的生长;夏季高温时期应采取有效的降温措施,以降低地温,使根正常生长。 Strawberry belongs to Rosaceae and is a perennial herbaceous plant. Because of its high economic value and wide adaptability, it is suitable for annual production of facility agriculture. At the same time, because strawberry is a shallow-rooted plant, the root system is more sensitive to the requirements of environmental conditions, especially the requirements of temperature, which shows that it is neither resistant to high temperature nor low temperature. The critical temperature for the growth of strawberry root system is 2-5°C, at -8°C it will be damaged by freezing, and at -12°C it will freeze to death. The optimum temperature for root growth is 13-23°C, the root growth is slow above 25°C, and the maximum temperature is 35°C. Therefore, in strawberry management, effective heating measures must be taken in winter to increase the ground temperature to ensure the safe overwintering of the root system and promote root growth; effective cooling measures should be taken during the high temperature period in summer to reduce the ground temperature and allow the roots to grow normally.

冬季,由于日光温室面积大,如果采用传统的热水管道加热方式对日光温室环境气温进行调节,很难达到整体的升温的效果,并且极其容易出现局部高温,局部低温,造成草莓植株生长不一致,甚至出现萎蔫的现象。同时当进行人工加温时,由于地温的升高存在明显的滞后,极易造成当气温达到草莓植株适宜生长温度时,根圈温度仍处于较低值的现象,这种现象致使草莓根系活力降低,营养吸收变缓,不能满足对地上部分营养供给的需求,造成草莓植株生长缓慢,甚至停止生长。夏季高温时期,白天的日光温室气温和地温都超过了草莓植株的适宜温度,草莓生长受到抑制。如果采用传统的湿帘-风机循环降温方式对日光温室环境气温进行调节,可以达到降低气温的效果,但与此同时,日光温室内的空气湿度会迅速的增加,不利于草莓植株进行光合作用且极易造成病虫害的发生。因此,实际生产中日光温室中这种气温和地温的变化现象对草莓的生长是非常不利的,要改善这种现状,环境调控能力的水平的提升是必需的技术途径。 In winter, due to the large area of the solar greenhouse, if the traditional hot water pipeline heating method is used to adjust the ambient temperature of the solar greenhouse, it is difficult to achieve the overall temperature rise effect, and it is extremely easy to have local high temperatures and local low temperatures, resulting in inconsistent growth of strawberry plants. There is even wilting. At the same time, when artificial heating is carried out, due to the obvious lag in the increase of ground temperature, it is very easy to cause the phenomenon that when the temperature reaches the suitable growth temperature of strawberry plants, the temperature of the rhizosphere is still at a low value, which leads to the decrease of strawberry root vitality. , nutrient absorption slows down and cannot meet the demand for nutrient supply to the aboveground part, causing the strawberry plants to grow slowly or even stop growing. During the high temperature period in summer, the daytime solar greenhouse temperature and ground temperature both exceeded the suitable temperature for strawberry plants, and the growth of strawberry was inhibited. If the traditional wet curtain-fan circulation cooling method is used to adjust the ambient temperature of the solar greenhouse, the effect of reducing the temperature can be achieved, but at the same time, the air humidity in the solar greenhouse will increase rapidly, which is not conducive to the photosynthesis of strawberry plants. Very easy to cause the occurrence of diseases and insect pests. Therefore, the change of air temperature and ground temperature in the solar greenhouse in actual production is very unfavorable to the growth of strawberries. To improve this situation, the improvement of the level of environmental regulation is a necessary technical approach.
